Does anyone know how I could integrate a photo gallery and shopping cart on C 5.7?

I've just taken hundreds of photos of some events and lots of people want to purchase. So somehow I want to bulk upload hundreds of shots and when someone is interested in an image they click on that image and it takes them to a cart. I don't want to deal with individual product descriptions and manually upload each image to its own page. C5 is my native web app but it's likely limited in this area. Otherwise is there is any way to pass a product link to an external shopping cart? People may choose multiple photos in a series so it could be clunky.

I'm not selling long term, just the post-event glow, so I don't want to enter into yearly subscriptions with the bigger commerce outfits until I test the waters. Just looking at C5 alternatives for rapid setup.
